Finding Sherlock

The Story

Last message received from Sherlock Holmes is as follows:
"Watson, my good chap, I have received an urgent request for my services. I am not accustomed to taking cases at the drop of a hat, but this one has piqued my interest. If you do not hear from me by this time tomorrow there may be cause for concern. You know my methods Watson. Speak soon.”
The deadline has passed and there is still no sign of Sherlock Holmes! Now you must use your deductive skills to find Sherlock!
